Electrical assembly with a housing

The invention relates to an electrical assembly with a housing in which there are electrical components that are mounted on mounting plates and are electrically connected to one another, with electrical operating and display elements protrude through corresponding openings in the front panel of the housing.

The well-known KoriS-WoU-Ji ovifi> i € LG.K + | r i scher assemblies with

a housing are usually designed in such a way that the electrical components are mounted individually on a chassis or combined in groups on separate mounting plates. The operating and display elements sit on the front panel and are electrically connected to the Bauelemen th on the chassis by wiring. The front panel is usually screwed to the chassis and a cover. This design has some disadvantages with regard to simple assembly and service work. The front panel with the operating and display elements cannot be easily removed because of the wiring. The same difficulty arises when assembling and replacing components and assemblies that are located inside the housing . In improved constructions, the operating and display elements sitting on the front panel are electrically connected to the components and assemblies inside the housing via Steckverbin, which in turn are also electrically connected via plugs attached to the chassis. In some designs, the operating and display elements are attached directly to the assembly to which they functionally belong and protrude through appropriate openings in the front panel so that they are no longer connected to it. Another disadvantage of the known constructions is the design of the housing. For example, if there is a requirement for a basic version of an electrical assembly with a housing through additional electrical assemblies

To expand eirxex · type series, a series would have to be different large housing made and placed in stock v / earth, which would be quite time-consuming and expensive.

The invention is based on the object of a simple, economical construction of electrical assemblies with to create a housing that makes it possible to use simple Means to vary the length of the housing and thereby with the lowest possible design and manufacturing effort to obtain a series of electrical assemblies with a housing.

This object is According to the invention achieved in that the housing is substantially in cross section the shape of a XJ-profile, said U ~ limb _s which two Seitenwän-, de of the housing form, and the connecting part forming the front panel of the housing of one piece exist and the length of the U-profile is identical to the length of the housing, wherein electrical assemblies in the form of mounting plates carrying electrical components are attached to the housing lying in one plane and arranged in a row.

In the accompanying drawings, an embodiment of the Invention shown, which is explained in more detail below. Show it:

In FIGS. 1 to 3, I denotes a housing which has the i'Ti cross section essentially in the form of a U-profile. The two side legs of the U-profile form side walls 1.1, 1.2 of the housing 1, while the connecting part between the two side legs forms a front plate. The side walls 1.1, 1.2 and the front plate 1.3 consist of one piece. The four edges of the front plate extend beyond the side walls 1.1, 1.2, so that a faultless retractable mounting of the electrical assembly in the opening of a higher-level assembly is possible addition 17th < The U-profile is preferably made of metallic material and is manufactured using suitable conventional manufacturing processes and stored in the usual lengths. A plastic with sufficient strength properties can also be used as the material for the U-profile. The manufacture of a certain type of housing is very simple, as it can be achieved by cutting off the required

Length of the U-profile bar. With 2, 3, 4, 5, 6, 7 electrical assemblies are beaeichaet, which can be pushed onto the housing 1 at the rear. In the end position, the assemblies rest on the side walls 1.1, 1.2 and are held on the housing 1 by springs 8, which are attached to the assemblies and snap into grooves 9 located on the inner surfaces of the side walls 1.1, 1.2 Electrical assembly 2 consists of a printed circuit on which an illuminated pushbutton switch 10, two contact carriers 11 and several screwless connection terminals 12 are attached. A push button 10.1 of the illuminated push button switch 10 protrudes through an opening in the front panel 1.3. It is not permanently connected to the other parts of the illuminated pushbutton switch and consists of translucent material, so that the switching state indicated by a lamp 10.2 can be easily recognized. The illuminated pushbutton switch 10, the contact carrier 11 and the screwless connection terminals 12 are correspondingly electrically connected to one another by printed cable runs. There are contacts 13 on two screwless connection terminals 12 . When the illuminated pushbutton switch 10 is actuated, a contact bridge 10.3 is pressed against the contacts 13 and thus an operating circuit is closed after a closed circuit has been opened. The electrical assembly 3 consists of a printed circuit 3.1 on which an indicator lamp 14 and two screwless connection terminals 12 are attached. The light of the indicator lamp 14 is from

a reflector 15, but it is shielded by a transparent cover inserted in the front panel 1.3 16 visible. The indicator lamp 14 and the screwless connection terminals 12 are analogous by means of printed cable runs electrically connected to each other. The electrical assemblies 4, 5, 6, 7 are also no further the same or different electrical components shown, such as resistors, diodes and transistors. Of the electrical connection and the electrical connection of the assemblies to one another is made using lead wires, which are plugged into the screwless connection terminals 12. In Fig. 3 it is made clear how by Varying the housing length by adding e.g. a or two electrical assemblies from one assembly type I into assembly types II or III.

If the electrical assembly with a housing is used, for example, as a floor panel for elevator systems, it is by installing it in a wall or a door post 17 sufficient Protected against dirt and contact with the electrical connections. In other cases one is not Cover hood shown further, which is pushed onto the housing 1 from behind and with it in a suitable manner is connected, provided.
